Reaction Steps

A mixture of 5-benzyl-2-chloro-4-[2-(2-hydroxyethoxy)ethylamino]pyrimidine (3.50 g, 12.08 mmoles), ethanol (190 mL) and 10% Pd on carbon (Aldrich) (0.84 g) was shaken in to presence of hydrogen at 2-3 atm for 17 hours. The reaction mixture was filtered through a pad of CELITE®, and the filtrates were spin evaporated in vacuo. The residual syrup was dissolved in dichloromethane (40 mL) and washed with water (20 mL) brine (20 mL) and then dried over sodium sulfate. The dry solution was spin evaporated in vacuo to give a residue that was triturated under hexanes to give 0.15 g (5% yield) of 5-benzyl-4-[2-(2-hydroxyethoxy)ethylamino]pyrimidine as a white solid, mp 86-87° C.
